If you have a shorter reach and you get in close youll be able to have better punching angles than the guy with the longer reach = more power in your punches. In a controlled environment like boxing or to a lesser extent MMA where you can always disengage by forcing a clinch reach is much more advantageous because you can in a sense reset the fight and keep on getting free hits when the guy with the shorter range guy is trying to get within striking distance.

FaZe was a joke on Overpass - the thought of those two nice guys punchning each other is just ridiculous and not funny. Is violent fantasies some sort of a joke in Brazil? Because that would explain some things about some statistics I've read....
